FILTER.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed April 22. 1907, Serial No. 369,539,

To all. "whom it may concern:

Be it known that l, STANLEY S. MON- 'ranrn, a .'itizen of the UnitedStates, residing at Canton, in the county of Bradford and State of lenns"ania, have invented certain new and us u improvements in Filters and Ido dez'lr 0 the following to be a full, clear, and ex: description ofthe invention, such will enable others skilled in the art to which itappertalns to make and use the same.

This invention relates to improvements in water filters.

The object of the invention is to provide a iilter adapted to beoperated by gravity, and having means whereby the sediment and loosebacteria contained in the water will be caused to settle to the-bottomof a filtering chamber instead of penetrating the filtering medium.

A. further object is to provide a filter having means whereby the waterwill be thoroughly sterilized and the germs or disease organisms thereindestroyed, said sterilizing means also eliminating all possibility ofthe growth or culture of any bacteria in the :liliered wate With theseOlJjCCtS in view, the invention consists oi certain novel features ofconstruction, iombination and arrangement of parts as will be morel'ully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical sectional viewthrough a filter constructed in accordance with the inven tion; and Fig.2 is a detail side view of the inner filtered water ri'weptacle, and thedis charge pipe connected thereto removed ,i romf the fil er.

Referring more particularly to the drawings, l denotes the outercylinder or water receptacle adapted to contain unfiltered water, saidcasing or 1 3C( "'Cl8 being provided on its upper end \i' l a removable2, and on it." wer end with a flanged 2. ennevted o one side of thelower end scent to oli faucet, l.

j'sl'iililgtld in tl casing l. and supported upon the bottom thereof, isa copper steril' izing cylinder, aid cylinder being open at its upperand lot. oi. ends and provided near its upper end with an annular head6, upon whicliis adapted to re t a removable perforated top, '7. Thecylinder .5 is highly polished on its inner and outer sides, therebygreatly facilitating its sterilizing properties.

Arranged in the cylinder 5 is a filtered water receptacle, 9, saidreceptacle bein preferably in the form of a closed meta l cylinder, theside walls of which are periorated about three-fourths of the distancedown from the up er end of the same, the closed up er end 0' thereceptaclebeing also erforated as shown. Connected with the ottoin ofthe receptacle 9 is a centrally disposed water discharge pipe 10 whichis provided a suitable distance below the receptacle with an elbow orbend, and extends therefrom horizontally through the wall of the casing1, said projecting end of the pipe e being threaded to receive a faucet12. T ends of the pipe 10 and the faucet 12 are provided with annularflanges or washers, by means of which a water-tight engagement isprovided between said parts and the wall of the filter.

The receptacle 9 is covered by a brass cloth screen, 13, over which isar anged a bag-like screen, 14;, which is preferably constructed ofasbestos cloth, and between said asbestos cloth screen and the brasscloth screen, 12, is arranged a coverin of fine filtering material,which is preferab ly in the form of mineral charcoal, 15. The lower endsof the asbestos cloth screen, 14, are brought around beneath thefiltered water receptacle, 9, and are secured to the pipe 10 by a copperwire fastener. tos screen is arranged a second bag-like screen, 16,which is formed of brass or asbestos cloth, preferably the latter, andbetween said outer screen and the screen 1 1 is arranged a cover offiltering material, 17, which is preferably in the form of bone black.The lower edges of the outer screen 16 are brought around beneath thegalvanized steel plate or disk, 18, which is secured to the pipe 10below the receptacle 9 and forms a support for the filtering material,17.. The ends of the screen 16 are secured to the pipe 10 by a 00' perwire fastener, as shown.

T e sterilizing cylinder 5 is provided in its lower edge with a notch orrecess, 19, which, when the cylinder is in place, is adapted to engagethe horizontal portion of the pipe 10, thus permitting the cylinder torest firmly on the bottom of the casing, l. Secured to the elbow or.bend of the pipe 10 is a galvanized steel supporting plate or disk, 19',which is Over the asbesand that said matter will gradually settle to thebottom of the filter instead of penetrating the filtering screens andmaterial, whereby said screens andfiltering material Will be kept cleanand their filtering qualities preserved, whereby thcy will remainellcctivc in operation for a considerably greater period than would hethe case should the sediment and foreign matter be forced into orpermitted to adhere to the surface of the filtering material.

The entire filtering mechanism m be readily removed for cleaning orother purpose, by unscrewing the faucet l2 and disengaging the end ofthe pipe 10 from the open ing in the casing 1, after which the filteringmechanism may be removed from the casing and readily taken apart.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters-Patent, is:

l. A filter comprising a casing-or receptacle for unfiltered water, aninner filtered "(21" ter receptacle having a perl'oratcd upper portion,a discharge pipe connected with said inner receptacle, a faucetrcmorably connected to the outer end of said pipe, a series of filteringscrecns arranged over said inner filtered water receptacle, layers oifiltering material arranged between said screens, and a coppersterilizing cylinder arranged around said filtering nmclianism,substalnially as described.

2. A liltcr comprising a casing or receptacle lor unfiltered atcr, aninner filtered water rcccptacle luiving a j'XIfOIziltKl upper portion, adischarge pipe connected with said inner receptacle, a i'aucet rcmovahlyconnccted to the outer end of said pipc,a series scenes of filteringscreens arranged over said inner filtered water receptacle, layers offiltering material arranged between said screens, a copper sterilizingcylinder arran ed around said filtering mechanism, said' cy 'nder havingpolished inner and outer Walls, and a pertorated top removably supportedin the upper end of said cylinder, substantially as described. 3. AWater filter comprising an outer casing or receptacle for unfilteredWater, a drawoff faucet arranged near: the lower end of said casing, afiltering mechanism arranged in said casing, a draw-0E pipe connected tosaid filtering mechanism, and a sterilizing cylinder arranged aroundsaid filtering mechanism, substantially as described.

4. A water filter comprising an outer cas ing or receptacle forunfiltered water, an inner filtered Water receptacle having a perforatedupper portion, a draw-off pipe con' nected to said inner receptacle andadapted to form a support for the same, a brass cloth screen arrangedaround said inner Water reing n'iaterial arranged over said brass clothscreen, a bag-like asbestos screen arranged over said filtering materialand secured at its lower end to the discharge pipe beneath said filteredWater receptacle, a layer of bone black filtering material arranged oversaid asbestos screen, a galvanized supporting disk arranged on saiddischarge pipe to sup ort the filtering material, an outer bag-like asestos screen arranged over said outer layer of filtering material andsecured at its lower open end to said. discharge .pipe below saidgalvanized plate, a polished copper sterilizing cylinder arranged aroundsaid filtering mechanism, a perfo rated top removably arranged in theupper end of said cylinder, anda supporting isk secured to saiddischarge pipe to support said filtering mechanism, substantially asdescribed.

in testimony whereof I have hereunto set my hand in presence of twosubscribing Witncsses.
